Network Working Group Request For Comments: 1304 T. Cox K. Tesink Editors Bell Communications Research February 1992 Definitions of Managed Objects for the SIP Interface Type Status of this Memo This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets.

1. The Network Management Framework The Internet-standard Network Management Framework consists of three components. They are: RFC 1155 [3] which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management. RFC 1212 [9] defines a more concise description mechanism, which is wholly consistent with the SMI. RFC 1156 [4] which defines MIB-I, the core set of managed objects for the Internet suite of protocols. RFC 1213 [6], defines MIB- II, an evolution of MIB-I based on implementation experience and new operational requirements. RFC 1157 [5] which defines the SNMP, the protocol used for network access to managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. 2. Objects Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) International Standard 8824 [7] defined in the SMI. In particular, each object has a name, a syntax, and an encoding. The name is an object identifier, an administratively assigned name, which specifies an object type. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the OBJECT DESCRIPTOR, to also refer to the object type. The syntax of an object type defines the abstract data structure corresponding to that object type. The ASN.1 language is used for this purpose. However, the SMI RFC 1155 [3] purposely restricts the ASN.1 constructs which may be used. These restrictions are explicitly made for simplicity. The encoding of an object type is simply how that object type is represented using the object type s syntax. Implicitly tied to the notion of an object type s syntax and encoding is how the object type is represented when being transmitted on the network. The SMI specifies the use of the basic encoding rules of ASN.1 International Standard 8825 [8], subject to the additional requirements imposed by the SNMP. SNMP Working Group [Page 2]
2.1. Format of Definitions Section 4 contains contains the specification of all object types contained in this MIB module. The object types are defined using the conventions defined in the SMI, as amended by the extensions specified in RFC 1212 [9]. 3. Overview These objects are used when the particular media being used to realize an interface is a SIP interface. At present, this applies to these values of the iftype variable in the Internet-standard MIB: sip (31) For these interfaces, the value of the ifspecific variable in the MIB-II [6] has the OBJECT IDENTIFIER value: sip OBJECT IDENTIFIER ::= { transmission 31 } The definitions contained herein are based on the SIP specifications in Bellcore TR-TSV-000772 and TR-TSV-000773 [11,12]. The SIP (SMDS Interface Protocol) protocol stack is defined as follows in TR-TSV-000772 [11]: SIP Level 3 [11] SIP Level 2 [11] PLCP [12] DS1 or DS3 [12] The PLCP (Physical Layer Convergence Procedure) adapts the capabilities of the transmission system (DS1 or DS3 formats) to the service expected by SIP Level 2. Managed objects for DS1 and DS3 Interface Types are defined in RFC 1232 [13] and RFC 1233 [14] respectively (and amended in RFC 1239 [17]), and can be utilized for management of SIP interfaces. This document defines managed objects for the remaining protocol levels of the SIP Interface Type. This document does not specify objects for the management of subscription SNMP Working Group [Page 3]
or configuration of Subscriber-Network Interfaces (SNIs). Those objects are defined in Definitions of Managed Objects for SMDS Subscription [18]. Bellcore requirements on these objects are specified in TA-TSV-001062 [16]. 4.
